Enter a scale such as 50% or 150% and the tool multiplies both width and height. Each image keeps its own proportions, which suits a mixed set of photos.
For common scales, browse the percentage presets, which show the result on common photo sizes.

How the presets in this category work
Each preset below fills in a ready-made value, so you can skip typing it. Open any of them, add your photo, and the editor shows the settings already applied. You can still change every value before downloading: the preset is a starting point, not a lock.
If your exact value does not exist as a preset, use this page to enter your own. The result is processed in your browser with Lanczos-3 resampling for scaling, and is never uploaded.
How to resize an image in percentage %
- Add your image. Select a photo or drag it onto the box above. JPG, PNG, WebP, AVIF, HEIC and BMP files are accepted, and the file stays on your device.
- Enter your size. Type the width and height you need and choose the unit. The aspect-ratio lock keeps the proportions unless you turn it off.
- Download the result. Click resize and save the file.
